1.16.5

• Fixed: Refunds could not be processed properly because of a mistake when calling the woocommerce_order_after_calculate_totals action. We assume the object is always a subscription, when it is not.
• Fixed: Properly stop checking for a gateway change when a gateway change succeeded.
• Fixed: Listen for total recalculation instead of a change in orders items when making sure we update the subscription price in Vipps whenever a Vipps subscription's price changes.
• Fixed: Updating a subscription. Campaign period was not being serialized properly when calling ->set_period(...)
• Fixed: Added a missing file that was not uploaded due to a mistake when committing files to SVN.
